Numerous job openings—many of them part time—should be available due to the industry’s large size and high replacement needs. Young workers age 16 to 24 hold one-third of grocery store jobs. Cashiers and stock clerks account for one-half of all jobs.
The grocery store industry is made up of supermarkets and convenience stores that do not sell gas. Stores in the grocery store industry sell primarily food items, including perishable foods, and may sell some nonfood items, but they do not specialize in selling certain types of foods, such as just meat, seafood, or health food. Stores that sell a mixture of food and more general merchandise, such as supercenters or warehouse club stores, are not in this industry.

Traditional supermarkets sold mostly fresh meats and produce, canned or packaged goods, and dry goods such as flour and sugar to people who lived in the neighborhood. They also usually stocked a few nonfood items used in preparing home-cooked meals, such as aluminum foil and paper napkins. These days supermarkets sell a wide range of traditional grocery items, general merchandise, and health and beauty products, plus a wide assortment of prepared foods, such as hot entrees, salads, and deli sandwiches for takeout. Most supermarkets have several specialty departments that may include seafood, meat, bakery, deli, produce, and floral. Nonfood items that can be found at larger supermarkets include household goods, health and beauty care items, pet products, and greeting cards. Some of the largest supermarkets may have concession counters, hot food and beverage bars or food courts, plus seating areas where patrons can eat while on the premises. In addition, many grocery stores offer catering services, automated teller machines, a pharmacy, postal services, and drop-off locations for film processing, drycleaning, and video rentals. Some grocery stores may lease space to banks, coffee shops, and other service providers, but these services are usually not performed by the grocery store.
Convenience stores typically sell a limited line of high-convenience items and food basics, such as milk, bread, beverages, and snacks. Some also offer readymade sandwiches and other prepared foods for immediate consumption along with an assortment of nonfood items, such as magazines. Most are also open longer hours than a typical supermarket.
